Let's Make It
Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain jars well before filling.
Crush black raspberries thoroughly, one layer at a time. (Press half of pulp through a sieve to remove some of the seeds, if desired.) Measure exactly 3-1/2 cups prepared fruit into 6- or 8-qt. saucepot. Stir in lemon juice.
Stir sugar into prepared fruit in saucepot. Add butter to reducing foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)
How to Measure Precisely
To get exact level cup measures of sugar, spoon sugar into dry metal or plastic measuring cup, then level by scraping excess sugar from top of cup with straight-edged knife.
